i have a very good friend. his (her) name is friends are very important in our life. i think one cannot live without friends. the most important thing for being good friends, to my mind, is to be ready to help one another in any situation, nevertheless how difficult it is, to support one another and to solve all the problems together. and never mind, that the friends may have different interests and hobbies, different likes and dislikes. they say that the friend in need is a friend indeed. i think it is really so.   my friend and i always do our best to help one another. we discuss all our troubles and try to find the best decision in any situation. my friend is a very good, kind and clever boy (girl). we often spend our free time together. it is not very easy now, because both of us are very busy — we are going to enter institutes and have a lot of work to do.   my friend is going to become a doctor (a teacher, an engineer, a lawyer). our future professions are different (the same) and the subjects we have to study are different (the same) too, but (and) we like to work together and to help one another in our study.   when we have some free time, we go for walks, read and discuss books, watch films, go to discos or play computer games. playing computer games is our hobby. both of us are fond of sport. we go in for swimming (tennis) and often go to the swimming pool (tennis court) together. we are football fans and we like to watch and discuss football matches on tv or to go to the stadium. i love my friend very much. i think he (she) is a true friend. our friendship is very dear to me and i try to do my best to be a good friend too.

Dear Mary,
Thank you for your letter. I'm glad that you''re interested in Russian history.

Russia is one of the largest countries in the world. The west territory of Russia lies in the eastern part of Europe and the northern part of Asia. Russia is washed by twelve seas and three oceans. The capital of the Russian Federation is Moscow, with the population of about 10 million people. The longest rivers are the Volga in Europe and the Ob, the Yenisei and the Lena in Asia. The largest lakes are Ladoga and Baikal. Baikal is the deepest lake in the world and its water is the purest on earth. The history of my native country is great! Russia is famous for its achievements and outstanding personalities like Petr I, Stalin and Gagarin.

Sorry I have to finish my letter because I have to do my History homework. 
I hope I helped you!
Write soon.
Best wishes,
Tanya
